Filed: 1933-11-08
Abstract: 428,373. Stays; fastenings. TAILBY, N., Spon Lane Mills, Houghton Street, West Bromwich. Nov. 8, 1933, No. 31056. [Classes 44 and 65 (i)] A stay and fastening for windows comprises a peg c fixed to one of the relatively movable members (the fixed frame in the form shown) for engagement by a catch f pivoted at j to the other member (the sash in the form shown), the catch f having a recess g, of U -shape in plan, at one end in its lower part and a stay or handle k pivoted to the catch on an axis l at right angles to the catch pivot and formed with holes m for engagement with the peg c to hold the window in adjusted open position.

Title: Krypton laser
Inventor: YAMAMOTO MANABU
IPC: H01S3/22
Filed: 1969-06-19
Abstract: 1,263,500. Lasers. HITACHI SEISAKUSHO K.K. 19 June, 1969 [21 June, 1968], No. 31169/69. Heading H1C. In a krypton laser pumped by an electric discharge within a capillary tube containing the active medium, termination of laser output by the pinch effect is prevented by operating the discharge under conditions of pressure and current which lie above the line plotted in the figure. A minimum current of 500 A/cm.<SP>2</SP> is required, and a magnetic field of 600-1200 gauss may be applied along the tube axis to enhance output. The use of such a magnetic field increases the slope of the plotted line, so that a higher gas pressure is required for stable operation at a given current. The maximum pressure used should be restricted to three times that given by the plotted line to avoid undue loss of output. Argon, neon and helium may be used with the krypton, the total pressure of the gases being that determined from the figure. Without the magnetic field, the initial pressure P (torr) is given by P # 1À2 x 10<SP>-3</SP>j, where j is the current density (amps/cm.<SP>2</SP>). With the field, P # 1À9 x 10<SP>-3</SP>j.

Abstract: 917,064. Sectional boilers. IDEAL-STANDARD Ltd. Sept. 14, 1959 [Sept. 18, 1958], No. 31245/59. Class 123 (2). In a sectional hot water boiler comprising a number of juxtaposed sections 1,2. connected at their top and bottom portions respectively by nipples 3 and wherein the cold water inlet and hot water outlet pipes 4, 4a enter lower and upper orifices in the end section 1, short circuiting of water through this end section is prevented by the provision of a flow restricting means consisting of a cylindrical sleeve 6 of resilient material which is fitted into the cavity at the top, or the bottom, of the section 1 between the outlet, or inlet, pipe and the adjacent connector 3. The sleeve is perforated at 7 and, when in position, has an open slot 8, the water flowing through the section 1 being constrained to pass through the holes 7 and slot 8 which are of such total area that the flow in the end section is substantially the same as that caused by thermal circulation in the other sections.

Title: Improvements in registering mechanism
IPC: B67D7/08
Filed: 1926-02-01
Abstract: 270,185. Arnold, C., (Gilbert & Barker Manufacturing Co.). Feb. 1, 1926. Counters actuated by reciprocating-mechanism. - A registering-mechanism is operated step by step as a setting-handle or like part is moved away from a zero position to one or another of a series of fixed positions, this movement being registered shortly after leaving one position and considerably before reaching the next. The mechanism is particularly designed for apparatus for measuring liquids, and is arranged so as to register half the quantity to be measured as the handle &c. is moved forwards from the zero position, and the other half during the return movement. Fig. 1 shows a mechanism wherein a setting-handle 106 adjusts a rack rod 104, 105, by means of which a quantity of liquid to be delivered is determined. The setting is determined by stops 120, 130. To enable the handle to pass the stops 120, it is made in two parts connected by a spring pivot 122. The stop 130 at the zero position prevents anti-clockwise rotation of the setting-handle, and clockwise rotation from the zero position is prevented by a spring stop which projects through the dial and engages in a recess in the arm 106. It may be withdrawn manually through an aperture in the underside of the casing. The registration is effected by a totalizing-counter 140 of the cyclometer type, actuated by a step-by-step ratchetwheel 146, with twenty teeth, levers 152, 156, and a disc 160 on the edge of which is a series of V-shaped notches 162, into which, as the disc is rotated by the arm 106, drops the end 158 of the lever 156. Since the disc 160, when rotated in either direction, actuates the counter, one half of the quantity sold will be registered in the clockwise movement of the arm 106, and the other half in the reverse movement. A cam 174 on the spindle 100 and a rod or lever 176 may be used to lock or unlock the liquid-supply mechanism. After the arm 106 and the rod 105 have been set, a controlling part of the liquid-supply mechanism is held out of a predetermined position, and the rod 176 is held against a nat 180 on the cam and prevents rotation of the arm 106. For fine adjustment, the stops 120 are eccentrically mounted.

Abstract: 1,152,704. Cast resin bushing. PERMALI Ltd. 22 July, 1966 [22 July, 1965], No. 31367/65. Heading H2C To prevent a resin bushing cast around two or more separated conductors 1 and 3 from contracting away from the conductors during cooling, those parts of the bushing adjacent each conductor are separated from each other by web 11. To improve the conductorresin contact, the surface of each conductor can be treated in various ways such as shot blasting or priming with paint. A deformable layer may be applied on to each conductor, adherent to the conductor but not to the resin, so that when the resin shrinks on to the deformable layer on setting a perfect seal will result.

Abstract: 1,272,674. Glow discharge lamps. SPERRY RAND CORP. 25 June, 1969 [5 July, 1968], No. 32040/69. Heading H1D. In a gas discharge indicator comprising a plurality of cathode segments 3 supported on pins 2 clear of the surface of a substrate 1, and a transparent anode member 16, an indentation 24 is provided in the surface of said substrate around each pin. The anode-to-cathode and cathode-to-substrate spacings are preferably such that, for a predetermined gas pressure in the device the cathode segments, when energized, glow on the viewing side only. Specified spacings are 0À03 inch and 0À005 inch respectively for a filling of mercury and neon at a pressure of 50 mm. Hg. The device is manufactured by sealing the pins 2 and anode connecting pins 14 and 15 through the glass substrate 1 so that the ends of the pins are flush with the surface on the viewing side and extend from the opposite surface a distance suitable for being received by mating sockets (not shown) for the application of operating potentials. The viewing side is then etched until the desired length of each pin is exposed, a cup-shaped depression 24 which reduces the effect of sputtering being formed about each pin by this operation. Anode member 16 comprising a glass substrate with a transparent conductive film 17 is spaced from substrate 1 by a plate 18 having a large aperture 19 and smaller apertures 20 and 21 through which extend springs 22 and 23 for contacting the anode. Anode member 16, spacer 18, and substrate 1 are hermetically sealed together. Alternatively, the member 16 and spacer 18 may be combined in a single moulded unit, or the anode may be a stainless steel wire mesh welded to pins such as 14 and 15. A gas filling tube 12 sealed to an aperture 11 in substrate 1 contains a mercury ampoule 13.
